ABSTRACT:
An air bag inflator includes a gas source and a gas outlet opening to allow flow of gas from the gas source into the air bag. A valve assembly for controlling flow of gas through the gas outlet opening includes a piston disposed in a cylinder. The piston has a surface against which the gas acts to move the piston in a first direction in the cylinder to allow increased flow of gas through the gas outlet opening. A honeycomb is disposed in the path of movement of the piston. The honeycomb is preferably made of aluminum or stainless steel. As the piston moves in the cylinder, the honeycomb crushes, resisting the movement of the piston.
